To wZZ whom it may concern:

Be it known that we, GEORGE H. S'ron'r and Lucius A. TURNER, citizens ofthe United States, residing at Denver, in the county of Denver and Stateof Colorado, have invented certain new and useful Improvements inWindow-Screens, of which the following is a specification.

Our invention relates to window-screens in which the screen fabric isheld to close the W111 the side edges of the fabric bearing against theouter faces of the blind-stop and its top and bottom bars secured attheir end edges to the opposing faces of the blind-stops. Fig. 2 is avertical section of the same. Fig. 3 is a perspective view of the insideof our improved screen constructed to screen either the whole or thehalf of the window -opening whether the contact of the side edges of theI fabric be upon the outer faces of the blind- 5 View of Fig. 5, brokenaway at one corner to stop or brick-mold and showing our new takeuplevers withdrawn from their fulcrum-sockets. Fig. 4 is a bottom view ofFig. 3 on line 0 d and showing the screen as applied to the frame,(shown as in Fig. 1,) but showing a thin metallic molding for securingthe wire fabric to the outside of the top and bottom bars. Fig. 5 is aninside view of the window frame and opening, showing our improved screenas secured at its top to the opposing faces of the brick-mold and amodification of the means of securing the top edge of the top rail fromlat eral, tipping and also showing the take-up levers inserted in theirfulcrum-sockets and acting to hold the screen fabric taut and againstthe outer face of the brick-mold. Fig. 6 is a partial view of the same,showing the take-up levers withdrawn and held in such position by theirhearing betweentheir retaining hooks and eyes. Fig. 7 is a verticalsection of Fig. 5 on the line a Z). Fig. 8 is an outside or front stopsto prevent lateral pull the screen fabric taut.

show the engagement of the take-up lever with its fulcrum-socket and itsguide-slot in the end of the bottom bar of the screen. Fig. 9 is apartial view similar to Fig. 8, showing thetop bar constructed forapplication to a window-frame having. a segment-head and especiallyshowing the function of the telescopetipping of the screen top bar.

The screen 1 is preferably of wire fabric and at its top is secured tothe outside side edge of a top bar 2, having in either end a slot 3. I

The bottom edge of the screen fabric is secured to the outside side edgeof a bottom or sill bar 4, provided at its end edges with slots 5 and onthe top of said bar and near its ends with screw-eyes 6 and hooks 7 andtake-up-lever bars 8. I Our new screen is designed to be attached to thewindow-frame at its top by hanging its top bar 2 by means of its endslots 3'on the studs 9, which are preferably in the form of screw-eyesand driven into the'opposing side faces of the window-frame whetherthese studs extend inwardly from the opposing side faces of thebrick-mold 10 or blindstop 11.

Its connection at its bottom is bymeansof inserting .the ends 12 of thetake-up levers 8 into fulcrum-sockets 13, let into the opposing sidefaces of the blind-stop or brick-mold of the window-frame.

side faces of either the brick-mold 'orblindstop of the window-frame andperfectly close when freed of the hooks 7 and inserted into.

their fulcrum-sockets 13 and pressed downward at their free ends beardown on the two ends of the top edges of the lower bar 4 and The freeends of the take-up levers are then hooked under the hooks 7 to maintainthe downward pressure on the screen, and as the hooks? are out near When:the top bar 2 is rigidly secured at the top of the window-opening inthe manner described and the bottom bar 4 is pulled downward, the sideedges of the screen fabric will fit tightly against the outthe free endsof the take-up levers there is a yielding throughout the length of thetake-u p levers and a consequential yielding on the screen fabric incase such fabric be subjected to undue strain.

Since the top edge of the top bar must parallel the under face of thehead of the windowframe, it is desirable that the top bar of the screenhave little or no vertical play, and with this object in view Wepreferably provide the end opening slot 3 in the bars 2 with insideside-opening entrances 14, adapted to receive the studs 9 uponpositioning the top bar with its top edge meeting and parallel with theunder face of the frame-head and with the side entrances 14 to saidslots 3 opposite said studs 9 and then pulling inward on said top baruntil the studs 9 meet the farther inside side walls of the verticalslots 3 and then dropping said bars until the studs 9 bear against theroof of the slots 3, at which position the top bar of the screen isstationary with respect to the frame by reason of the fact that itsinner sides bear against the outer vertical faces of the window-frame,blind-stops, or brick-molds, as the case may be.

The end slots 3 are conveniently constructed by first boring into thevery end edges of the side wall of the top bar for a distance reachingthe farther vertical wall of the vertical slot, which is obtained bychiseling from the end of the bar for a slight distance above the roofof the side bore and then chiseling for the entrance of the studsidewise to the vertical slot 3 from the inside of the bar for only sucha distance above the bottom of the vertical slot as to allow the sideentrance therein of the studs 9.

In the case of window-frames having a segmental head it is obvious thatthe bearing of the inner vertical walls of the slots 3 would beinsufficient to prevent the outward tipping of the top bar, and toprovide against this telescope-stops 15 of well-known construction areprovided in said top bars so as to project upwardly from the top edgethereof into sockets 16, let into the under face of the frame head, asshown in Figs. 9, 8, 7, and 5. In Figs. 5, 7, and 8 the telescope-stopsare shown as applied to a window-frame the under face of the head ofwhich is horizontal, and though the function of said telescope-stops isthe same as with a segment-headed frame their application in thesefigures is especially shown to illustrate the function of'saidtelescope-stops to prevent any outward tipping of the top bar when usedon these windowframes,which, by reason of their varied construction,necessi tate the use of a wide top bar.

Over the screen-fabric fastenings on the outer sides of the top bars isa stripof molding 17, extending above the top edge of the top bars forsufficient distance to provide for the drop of the same on its studs andbeyond each edge of the same to the edge of the screen fabric. Thismolding 17 also on the bottom bar may be constructed of thin metal, sothat when the screen is applied to a window-frame having outsideshutters it will not interfere with the closing of said shutters orblinds against the blind-stop, as there is usually a slight play on thehinges of the shutters. When used with shutters, the screen is hung tothe opposing faces of the blind-stop, as shown in Fig. 4. When thewindow-frames are not provided with shutters, the screen is preferablyhung to studs projecting from the opposing faces of the brick-mold, asshown in Figs. 5, 6, 7, 8, and 9, and in such a case the molding 17 ispreferably of wood and may be of any thickness. I

When the topbar of the screen is positioned as shown in Figs. 5, 7, and8, the mold 17 will extend above the top edge of the top bars and closethe opening between the under face of sets; but it is desirable thatthose insects which 1 enter the house at other points have means ofexit, and for this purpose an opening 18 is provided in thetop bar 2.This opening is preferably made by sawing out a slot from the under faceof the top bar upward and partially cutting themeeting face of the mold17, and such opening is preferably flared in both directions at thebottom, so as to give therethrough ready exit to the common fly, thewell-known tendency of which is to crawl upward and of which, as is wellknown, it is disinclined to crawl downward through an opening, so thatsuch an opening 18 is in a sense a fly-trap, since it affords ready exitfor flies upon the inside of the screen, but baflies their entrance.

For the reason that the screen fabric may stretch during thefrepeatedpressure thereon of the take-up levers to such a degree as to allow thebottom of the bottom bar no further movement to stretch the screen tautagainst the outer faces of brick-mold or blind-stop the eyed bearings 6are seated in the top edge of the bottom bar, so as to have adjustmentvertically. In the drawings this adjustment is shown to be obtained bysci'ew threads upon the stem of the eyes. Such an adjustment is alsodesirable in case the commercial screen fabric do not accommodate thecalculations for its stretch to the calculations of the adjustment ofthe bearings of the take-up lever on the bottom bar or thefulcrum-socket bearings in the inner faces of the opposing sides of thewindow-frame. The hooks 7 are like wise adjustable.

We claim a l. A screen for windows consisting of a sheet of screenfabric spanning the window-opening and having top and bottom horizontalframebars, of means for securing said top bar in rigid parallel relationto the under face of the head. of the window-frame, and means formaintaining the inner surface of the screen fabric at its side edgesclosely against the outer vertical faces of the window-frame consistingof take-up levers at both ends of said bottom bar having endfulcrum-bearings in the opposing faces of the window-frame and hearingson said bottom bar near its ends, hooks on said bottom bar between itsend take-up-lever bearings adapted to retain the depressed free ends ofsaid take-up-lever bars, for the purpose and in the manner substantiallyas described.

2. In a detachable Window-screen having only horizontal top and bottomframe-bars the top bar of which is fixed to studs projecting from theinner faces of the window-frame and the bottom bar of which is held downtoward the sill of the window-frame by take-up levers having afulcrum-socket bearing in the inner faces of the Window-frame,avertically-adjustable eyed bearing for said take-up levers located ontop of and near the ends of said bottom bar, hooks on top of said bottombar retaining the depressed free ends of said takeup levers passingthrough vertical slots in the ends of said bottom bars, substantially asdescribed.

3. In a window-screenof the class described, means for securing its topbar in fixed parallel relation to the under face of the windowframehead, means for holding the outer ver tical edges of the screen fabricclose against whereby to engage and retain the free ends of said take-uplevers, substantially as described.

4. A screen for windows consisting of a sheet of fabric closing thewindow-opening and contacting with the outer faces of the brick-mold orblind-stop and having top and bottom horizontal frame-bars, slots in theends of said top bar, stud-openings into said slots on the inner side ofsaid top bar adapted to receive studs projecting from the opposing facesof the windo Wframe and means for downwardly pulling said screen fabricadjustably against its fixed top-retaining means, substantially asandfor the purpose described.

In testimony whereof we afiix our signatures in presence of twowitnesses.
